ABSTRACT
OBJECTIVE@#To observe the therapeutic effect of needling technique (acupuncture for regulating spleen and stomach) on diabetic gastroparesis (DGP), and to explore its possible mechanism.@*METHODS@#A total of 128 patients with DGP were randomized into an observation group (64 cases, 4 cases dropped off) and a control group (64 cases, 4 cases dropped off). On the basis of intervention on controlling blood glucose by western medication, needling technique was adopted at Zhongwan (CV 12), Zusanli (ST 36), Yinlingquan (SP 9), Xuehai (SP 10), Sanyinjiao (SP 6), Diji (SP 8), etc. in the observation group, once a day. Mosapride citrate dispersible tablet 5 mg was given orally 3 times a day in the control group. The treatment was given 6 times a week in the both groups, and totally 4-week treatment was required. Before and after treatment, the DGP symptom score, serum content of transmembrane protein 16A (ANO1) were observed, and the clinical therapeutic effect and the safety were evaluated in the both groups.@*RESULTS@#After treatment, the each subitem score (belching, abdominal distension, inappetence, nausea and vomiting, epigastric pain, abnormal defecation) and the total score of DGP symptom were decreased in both groups (<0.05), the subitem scores of belching, abdominal distension, inappetence, nausea and vomiting and the total score in the observation group were lower than those in the control group (<0.05). After treatment, the serum contents of transmembrane protein 16A were reduced in both groups (<0.05), and that in the observation group was lower than the control group (<0.05). The total effective rate was 86.7% (52/60) in the observation group, which was superior to 70.0% (42/60) in the control group (<0.05). Subcutaneous hematoma occurred in 5 cases in the observation group, which was improved after cold compress without other particular intervention.@*CONCLUSION@#The therapeutic effect of needling technique on improving symptoms in patients with diabetic gastroparesis is superior to mosapride citrate dispersible tablet, its mechanism may be related to alleviating the damage of interstitial cells of Cajal (ICC).
ABSTRACT
Objective: To identify specific biomarkers that could improve early diagnosis of lung adenocarcinoma using matrix-assisted laser desorption/ionization (MALDI) technology. Methods: Serum samples were isolated from 17 patients with stage I lung adenocarcinoma and 17 age- and sex-matched healthy controls, and the serum proteomic profiles were obtained by matrix-assisted laser desorption ionization time of flight (MALDI-TOF) mass spectrometry. Results: Compared with healthy control group, two highly expressed potential biomarkers were identified with the relative molecular weights of 6631.64 Da and 4964.21 Da. The two best novel protein peaks were automatically chosen for the system training and the development of the constructed model. The constructed model was then used to test an independent set of masked serum samples from 15 lung adenocarcinoma patients and 22 healthy individuals. The analysis yielded a sensitivity of 93.3%, and a specificity of 95.5%. Conclusion: These results suggest that MALDI-TOF-MS ProteinChip technology is a quick, convenient, and high-output analyzing method that is capable of selecting several relatively potential biomarkers from the serum of lung adenocarcinoma patients and may have a clinical value in the future, and will provide clues to identifying new serologic biomarkers of lung adenocarcinoma.
